By analying the relationship between the construction of the periodical and the management of the medical quality, the author explained the positive effect of strengthening the former on level raising of the latter, She also proposes that the value of the periodical can be raised by the quality construction including superiority orientation and creativity development. In this way we will raise the additional value of the management of medical quality and provide a high-level information platform for the quality mangement of hospital.

Objective To evaluate the effect of liver transplantation(LT)on the prognosis in patients with intrahepatic cholangiocarcinoma(ICC).Methods A retrospective analysis was performed on 11 consecutive patients with ICC who underwent LT between October 2003 and November 2008 at our institution.The overall and disease-free survival rates were calculated by the Kaplan-Mayer method.Results The median survival time Was 9.0 months(2.5-53 months).The 1-,2-,3-and 4-year disease-free survival rate and overall survival rate of all the patients were 51.9%、51.9%、51.9%、51.9%and 50.5%、50.5%、50.5%、50.5%,respectively.The perioperative mortality and the recurrence rate were 0 and 43.5%,respectively.The survival rate and disease-free survival time of patients with recurrence were 2.5-10 months(mean 7.5 months)and 1-8 months(mean 3.8 months).Conclusions The prognosis of LT for ICC is rather poor.ICC patients with lymph node metastasis.vascular or bile duct invasion is contraindicated for LT.

OBJECTIVETo investigate the distribution and expression of corticotropin releasing factor (CRF) in spinal cord, hypothalamus and third ventricle of cerebrum, of the hypersensitive viscera rats, and to research on the mechanism of CRF in the hypersensitive vicera signal conduction pathway in IBS (irritable bowel syndrome) and to investigate possible active mechanisms of tongxie prescription on IBS.
METHODForty SD rats were divided randomly into three groups. The rats of model No. 1 were sensitized by injecting egg albumin into abdominal cavity. The rats of model No. 2 were sensitised by conditional stimulus and unconditional stimulus. The two model groups were both divided randomly into two groups. The five groups were given intragastric administration with Tongxie prescription or normal saline for four weeks. Then quantitative analysis of CRF in the lumbosacral spinal cord and brain of rats were achieved by immunohistochemical method and computerized image system.
RESULTThe sensitivity of the groups being treated with tongxie prescription were much lower than the model groups (P < 0.01). The immunohistochemical method showed that CRF was expressed in the lumbar intumescentia of spinal cord, hypothalamus and the diaphragmatic surface of third ventricle of cerebrum. The CRF positive index of the model groups was higher than that of the blank group (P < 0.01). The CRF positive index of the healing groups was lower than that of the model groups (P < 0.01). The CRF positive index of the healing groups was higher than that of the blank group (P < 0.01).
CONCLUSIONThe two model rats evoked by two different stimulation both appeared visceral hypersensitivity state. CRF is related to stress. The increase of CRF expression in the lumbar intumescentia of spinal cord, hypothalamus and the diaphragmatic surface of third ventricle of cerebrum showed that CRF is critical to the introduce of stimulus signal of vicera. Tongxie prescription can significantly decrease CRF expression. This is one mechanism to decrease sensitivity of hypersensitive viscera rats.

This study aimed to report the clinical characteristics and COMP gene mutation of a family with pseudoachondroplasia (PSACH), a relatively rare spinal and epiphyseal dysplasia that is inherited as an autosomal dominant trait. Clinical information on a 5-year-2-month-old PSACH child and his parents was collected and analyzed. Diagnosis was confirmed by PCR amplification and direct sequencing of all the 19 exons and their flanking sequences of COMP gene, and the mutation was further ascertained by cloning analysis of exon 10. The child presented with short and stubby fingers, bow leg, short limb dwarfism and metaphysic broadening in long bone as well as lumbar lordosis. A mutation c.1048_1116del (p.Asn350_Asp372del) in exon 10, inherited from his father who did not demonstrate any phenotypic feature of PSACH, was detected in the child. PSACH was diagnosed definitively by means of COMP mutation analysis, on the basis of the child's clinical and imaging features. The non-penetrance phenomenon of COMP mutation was described for the first time in PSACH.

Cannabinoid receptor type 2( CB2 R),a member of the G protein-coupled receptor( GPCR) superfamily,has a variety of biological activities,such as regulating pain response,resisting inflammation and fibrosis,and mediating bone metabolism. Some CB2 R regulators exhibit a good regulatory effect on bone metabolism. Cannabinoids in Cannabis sativa can cause psychoactive effects despite various pharmacological actions they exerted by targeting CB2 R. Therefore,it is of great significance to discover CB2 R regulators in non-Cannabis plants for finding new lead compounds without psychoactive effects and elucidating the action mechanism of plant drugs. The present study clarifies the discovery,structure,and physiological functions of CB2 R,especially its regulatory effects on bone metabolism,summarized CB2 R regulators extracted from non-Cannabis plants,and systematically analyzes the regulatory effects of CB2 R regulators on bone metabolism in animals,osteoblasts,and osteoclasts,to provide a scientific basis for the discovery of new CB2 R regulators and the development of anti-osteoporotic drugs.

Aim To investigate the impact and mechanism of Weichang'an Pill(WCA),its ethanol extract(EE),water extract(WE),and active ingredients on the contraction of isolated rat ileum smooth muscles induced by acetylcholine(ACh). Methods In vitro tissue bath experiment,WCA,EE,WE,or their active ingredients were added under the action of ACh,and then the contraction tension of isolated ileum smooth muscle from rats was recorded. The binding affinity ofthe active ingredients to the muscarinic acetylcholine M3 receptor was explored by molecular docking. Results WCA,EE,and WE were able to considerably inhibit the excitatory contraction of the ileal smooth muscles induced by ACh. Costunolide,dehydrocostus lactone,santalol,muscone,emodin,chrysophanol,physcion,crotonoside,magnolol,and honokiol were also significantly effective against ACh-induced ileal smooth muscle contraction. Conclusions WCA,EE,WE,and their active ingredients may help to promote intestinal smooth muscle relaxation by blocking the binding of the M3 receptor on the membrane of ileal smooth muscle with ACh.
